This would be really great; unfortunately, it is not simple to do, 
because a memory dump does not work. A form has some properties, which 
can be dumped in a file. Then it has a reference to every object the 
form contains: labels, buttons and so on. Those objects cannot be dumped 
in a file by the form, because the form does not know enough of them to 
do it - every single object must dump itself, and must be able to reload 
itself from the data in the file, calling constructors for every 
sub-object it contains, and so on. This means extend every single object 
to put methods in it for streaming. A lot of work.
